80 megabytes of statistical bathymetry data summarize sea depth across a 1-kilometer grid. The dataset contains mean depth, shallowest depth, standard deviation, and sample counts derived from multiple hydrographic surveys. It covers the Northwest Pacific Ocean from 0°N to 48°N latitude and 120°E to 180°E longitude.
Use Cases
- Model seabed terrain based on mean depth and standard deviation values.
- Identify shallowest points for navigation or habitat studies.
- Analyze depth variability across the 1-kilometer grid.
- Integrate statistical bathymetry with other oceanographic datasets.
Strengths
- Data volume is about 80 megabytes.
- Derived from multiple authoritative sources including GEBCO and J-BIRD.
- Covers a specific geographic region (0°N to 48°N, 120°E to 180°E).
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Last update date is unknown; freshness unverified.
